Abstract (en)
[origin: US4453087A] A scanning mechanism for a fast framing thermal imaging system such as a FLIR is disclosed. The scanning mechanism comprises two prisms which are canted with respect to one another and positioned in front of the final image forming lens of the FLIR. The two prisms are precisely counter-rotated with respect to one another by a drive train assembly and motor means. An annular timing disc is positioned about one of the prisms to enable an optically sensitive transducer to sense the rotational position of the prisms. The counter-rotating prisms function to enable the detector array of the FLIR to dissect the thermal image in a 2:1 interlacing technique.
